Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel material, enhanced by a passivated finish, provides excellent resistance to oxidation and chemical exposure, making it ideal for machinery, automotive, and electronic enclosures operating in corrosive settings. The 5/8" shoulder length with precise tolerances acts as a reliable pivot or spacer, maintaining component alignment while reducing wear. With a Class 2A thread fit and coarse UNC threading, it ensures quick, secure fastening in high-vibration environments, minimizing loosening over time. The dual socket and slotted drive offers flexibility for maintenance, supporting efficient disassembly in confined spaces.

Specification Summary & Compliance

This shoulder screw adheres to UNC 10-24 thread standards with a Class 2A thread fit for consistent dimensional accuracy.
